Prop 37 on this fall’s California ballot, pleasantly billed as the Right to Know campaign, would require labeling of food with genetically modified (GMO/GE) ingredients.

And even though health fears about GMO/GE products have been debunked by virtually every scientific authority to look into the matter — from the AMA to the World Health Organization, and including science reporting in such perhaps unexpected venues as Mother Jones and the Huffington Post — voters in a new Pepperdine poll still approve of the idea by a lopsided 69 to 22 percent. After all, how much could it cost just to put labels on foods?

We may soon find out. California’s fabled Proposition 65, enacted in 1986, requires the labeling of products that expose consumers to substances linked to cancer. That’s a pleasant-sounding idea too, but 26 years later the law has benefited almost no one but litigators.

The official proponent of the new Prop 37 — such a coincidence! — is an Oakland attorney who’s taken in millions in Prop 65 settlements.
